Product Description:
The MSK100C-0300-NN-M1-RG2-NNNN is an IndraDyn S synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It converts drive current into precise rotary motion for positioning axes and continuous-duty processes in industrial automation. This model uses a plain shaft to couple directly to gearboxes or load hubs. Feedback comes from an integrated optical encoder mounted in the motor, so the paired drive can track rotor position during speed and positioning tasks. That arrangement makes the motor suitable for machine axes that require repeatable starts, stops, and steady rotation under closed-loop control.
Cooling relies on natural convection, so heat is dissipated through the aluminum housing without auxiliary blowers. This supports installation where a simple motor design is preferred and reduces the need for separate cooling hardware near the axis. An electrically released holding brake delivers 70 Nm of static torque, allowing vertical axes to remain fixed when the drive is de-energized. Position data is provided by a multi-turn absolute encoder that uses optical scanning and outputs 128 signal periods per revolution over the Hiperface interface. Because the feedback system is absolute and multi-turn, the control system can retain position information across multiple revolutions. The housing is sealed to IP65, which helps protect the windings and bearings from dust and direct water jets.
The C-length build is paired with the size 100 stator core, and winding code 0300 gives the torque constant and electrical resistance used for medium-speed applications. Power and feedback connectors are located on the right side, which helps keep cable routing aligned with adjacent machine components. This placement can also reduce cable crossover where several axes are mounted in a row. Operation is specified from 0–40 °C, a range that suits most climate-controlled production areas. Insulation class 155 allows the winding system to tolerate temperatures above ambient during normal operation.
